The Toughest College Test You'll Ever Take If your professor asked you today to kick your social networking habits, do you think you could do it? Can you go without Facebook, cell phones, or the Internet for a week? For a day?

A University of Minnesota professor challenged her public relations class to go five days without media or gadgets that didn't exist before 1984.

Out of the 43 students in the class, just a handful made it even three days without new technology.

Among those who didn't, one student said, "My mother thought I died." How long could you go without any social media? What types of issues might you encounter without constant connections to your friends? How has social media impacted society? How has social media impacted businesses?
